Attention Detection in Virtual Environments Using EEG Signals: A Scoping Review

The competitive demand for attention is present in our daily lives, and the identification of neural processes in the EEG signals associated with the demand for specific attention can be useful to the individual’s interactions in virtual environments. Since EEG-based devices can be portable, non-invasive, and present high temporal resolution technology for recording neural signal, the interpretations of virtual systems user’s attention, fatigue and cognitive load based on parameters extracted from the EEG signal are relevant for several purposes, such as games, rehabilitation, and therapies. However, despite the large amount of studies on this subject, different methodological forms are highlighted and suggested in this work, relating virtual environments, demand of attention, workload and fatigue applications. In our summarization, we discuss controversies, current research gaps and future directions together with the background and final sections.

The Restorative Effect of the Presence of Greenery on the Classroom in Children’s Cognitive Performance

Studies developed in a scholar context report a restorative effect of nature on human beings, specifically in terms of the psychological recovery from attention fatigue and restored mental resources that were previously spent in activities that require attention. Studies usually compare the performance of children in schools with or without access to green spaces. In this study, the effect of introducing greenery into the classroom context was compared across time. The experiment was developed in two primary schools with pupils in different socioeconomic contexts, at three moments: before introducing an artificial green wall into the classroom, one month later, and one month after the introduction of vegetable pots. Results showed a significant increase in sustained and selective attention, and work memory between the experimental and the control group, notably in the third moment when vegetable pots were introduced. In the second moment (green walls), only the work memory (tested with the inversed number) showed a significant effect. Theoretical and practical implications are discussed in terms of nature’s role both in terms of natural and artificial elements and the cumulative effect of direct interaction with natural elements.

Restorative Effects of Classroom Soundscapes on Children’s Cognitive Performance

Previous studies have examined the restorative benefits of soundscapes on adults’ cognitive performance, but it was unclear whether those benefits would be possible for children. In this paper, two experiments applied a before–after design to explore the restorative effects of different soundscapes on children’s sustained attention and short-term memory, respectively, in a simulated classroom situation. In Experiment 1, 46 children aged 8–12 were first mentally fatigued by performing an oral arithmetic task and then were asked to conduct a sustained attention to response test (SART), in order to assess their attention fatigue. After that, a period of 3-min soundscape was presented, and SART was conducted again to examine their attention recovery. In Experiment 2, 45 children participated and the experiment procedure was the same as in Experiment 1, except that a digit span test (DST) was used instead to measure short-term memory. The results showed that music, birdsong, fountain sound, and stream sound facilitated greater recovery than other sounds in reaction time. Participants also showed better performance in short-term memory after exposure to fountain sound and stream sound, followed by music and birdsong. Those results confirmed the actual restorative effects of perceived restorative soundscapes on children’s cognitive performance.

Exploring restorative potential of biophilic servicescapes

PurposeThe purpose of this study is to explore the relationship between the biophilic stimuli present in the servicescape and restorative effects on psychological states among consumers. The research also examines moderating role of service contexts in this relationship.Design/methodology/approachThis empirical study applied a laboratory-like experimental design with one-shot treatment. About 566 usable responses were collected using six photographic images – three were biophilic environments and three were non-biophilic environments – for foura prioriservice contexts: hospital lobby, upscale restaurants, spa and bank lobby.FindingsThe tests of hypotheses confirm restorative effects of biophilic servicescapes on consumer’s psychological states, attention and mood, which, in turn, positively influence service preference. Further, the restorative effects of natural elements are found to vary across hedonic – utilitarian and experience – credence type service contexts.Originality/valueBecause of higher levels of natural stressors, consumers today likely have attention fatigue and depleted mood states, which, in turn, may have adverse effects on their service consumption behaviour. In this context, building upon theories from environmental psychology, findings of this study contribute by establishing restorative potential of biophilic servicescape. The study also establishes that natural elements in biophilic servicescapes influence service preference, which is mediated by consumers’ psychological states – attention and mood. Further, it demonstrates that consumers are more responsive with regards to such restorative effects of biophilic elements in contexts where they seek emotional, experiential value compared to rational, functional value.

Stimulant Use in the Management of Mild Traumatic Brain Injury: A Qualitative Literature Review

Objective: Mild traumatic brain injury (mTBI) often presents with cognitive complaints including difficulty with attention and concentration. As these symptoms resemble those of ADHD, stimulants may be a potential treatment for mTBI. This review evaluates the literature on the use of stimulants for the treatment of mTBI. Method: A systematic evaluation of the literature using six databases: Ovidmedline, Pubmed, psychINFO, CINAH, Embase, and Cochrane. Broad search terms were used and studies were included that evaluate the use of stimulant and stimulant-like medications in the mTBI population. Data extracted included stimulant type and dosing, symptoms targeted, outcomes, safety and tolerability, and if the study population had ADHD. Results: Nine studies were identified that met the inclusion criteria. Immediate release methylphenidate and amantadine were used for treatment. Methylphenidate had some impact on attention, fatigue, and depression. However, due to the limited number of studies and heterogeneity of study populations, symptoms targeted, and outcome measures used, meaningful conclusions regarding the effect of stimulants in mTBI could not be made. No study evaluated for the presence of ADHD within the study population, despite stimulants being the mainstay treatment for ADHD. Conclusion: PProspective studies on the use of stimulants in mTBI, that evaluate participants for a diagnosis of ADHD, are needed.

The reduction of directed attention fatigue through exposure to visual nature stimuli: Exploring a natural therapy for fatigue

This study compares the restorative effects on directed attention functioning following exposure to natural landscape images versus scrambled/distorted landscape images. Attention restoration theory (ART) provides an analysis of the stimuli and environment required for restoration of cognitive fatigue. According to ART, nature employs attention through a bottom-up process in which intrinsically fascinating stimuli from the natural environment itself modestly dominate attention. This allows the mechanisms responsible for top-down processing, which is necessary for directed attention, to recover and replenish. Unlike natural environments, urban environments employ attention through bottom-up stimulation, which forces one to overcome the stimulation using directed attention, thus not allowing for the recovery of directed attention mechanisms. This study looks into whether solely visual stimulation of natural environments is adequate for the restoration of directed attention mechanisms as measured with the “Attention Test” application. The mean completion time on the Attention Test game was significantly lower in the nature image group (M = 54.33) when compared to the scrambled image group (M = 62.04), thus validating the visual aspect of ART.

Interim results of neuropsychological analysis of the development of children with perinatal risks

This article presents a brief description of the normative mental development of the elder preschool children: features hemispheric interaction between the cerebral hemispheres, dynamic, spatial and motor praxis, memory, visual-objective, visual-spatial and acoustic-verbal gnosis and originality of speech, thought and attention. Besides, this article illuminates analysis of the interim data obtained in the course of neuropsychological investigation of cerebral organization of mental functions among preschoolers whose mothers have an anamnesis of various risk factors of perinatal pathology of the fetus. The analysis of the data illustrates that very often agenda had difficulties in carrying out tests for visual gnosis, audio-verbal memory, dynamic and spatial praxis. Also it was hard for children to compile stories for narrative paintings and series of narrative pictures. Besides, it was recorded that the majority of children have shown attention fatigue and instability of attention and the high level of exhaustion. So the interim results received on this level of experimental research illustrate the existence of tendency of defection in the process of formation of high psychic functions among children with different risk of development of perinatal pathology in their anamnesis. But in the cause of the insufficiency of experimental data it is to early to make strict conclusions concerning the concrete consequences of the different perinatal risks for brain organization of child’s psychic activity.
